Your initial pre flop action was super aggressive for 3C5C but for the love of God what are you putting him on and what hand are you trying to hit or rep on the turn and river? Where you planning on hitting a 4? Basically you've got a low 2nd pair on the flop and he could easily have AK amongst other hands with his aggro flop raise.
Anyway I'm just an online micros and live 1-2 and 2-5 guy so I probably don't have a right answering this.
